Impairment of Long-Lived Assets See "Impairment of Long-Lived Assets" in Note 1 to the financial statements in the Form 10-K for a discussion of the periodic reviews that Entergy performs whenever events or changes in circumstances indicate that the recoverability of long-lived assets is uncertain. Following are updates to that discussion regarding the Vermont Yankee nuclear power plant. First, as discussed in the Form 10-K, Entergy is seeking a Certificate of Public Good from the Vermont Public Service Board (VPSB) for operation of Vermont Yankee until March 2032. In June 2013, the VPSB completed hearings on that petition and established a schedule providing for proposals for decision and initial briefs to be filed in August 2013 and reply briefs to be filed in September 2013. Second, as discussed in the Form 10-K, the New England Coalition in December 2012 filed a complaint in the Vermont Supreme Court seeking an order to shut down Vermont Yankee while its Certificate of Public Good application is pending, and Entergy moved to dismiss that complaint. On March 25, 2013, the Vermont Supreme Court granted Entergy's motion and dismissed the complaint. Third, as discussed in the Form 10-K, Entergy appealed a January 2013 order of the VPSB that made ripe for appeal two earlier orders in which the VPSB had found that the state's timely renewal law, 3 V.S.A. § 814(b), did not apply to certain conditions in the orders issued by the VPSB in 2002 and 2006 precluding Vermont Yankee's operation after March 21, 2012. Briefing of this appeal has been completed and the Vermont Supreme Court has scheduled oral argument for October 2, 2013. Fourth, as discussed in the Form 10-K, in February 2013, the VPSB issued a notice allowing comments to be filed regarding Vermont Yankee's petition for a Certificate of Public Good to install a diesel generator to enable it to comply with the NRC's station blackout requirements. On June 6, 2013, the VPSB issued a Certificate of Public Good for the diesel generator, allowing construction to begin on a schedule that is expected to enable Vermont Yankee to meet the September 1, 2013 deadline for compliance with these NRC requirements. Impairment of Vermont Yankee in First Quarter 2012 See the Form 10-K for a discussion of the impairment charge recorded for the Vermont Yankee plant in the first quarter 2012.
